Harmless Fan Has Ribbon Blades (Jul, 1935)

I actually just bought one of these for my desk at work.

Harmless Fan Has Ribbon Blades
SILK ribbons, held in loops, form the blades of a harmless electric fan recently demonstrated at the Industrial Arts Exposition in New York. The ribbons give a standard pitch when rotating and are said to be able to throw a current of air ten feet away.

  1. Why not just use sharp big razor blades and encase them in a cage (like today’s fans)?

    ;)

    But seriously, whouldn’t it be easier NOT to have exposed fan blades? no matter if they’re harmless .

  2. That it is an interesting idea, I think soft rubber would be more practical for the paddles.

  3. They used to make rubber ones, my folks had a three blade rubber fan when I was little back in the 60s.
    The rubber eventually got brittle and I suppose the thing was as dangerous as a plastic bladed fan with no shroud. If the motor case hadn’t cracked and fallen apart it would probably still be around.

  4. I have had Caframo fans for years. They are much quieter and do a much better job of moving air than a caged fan that has a grille that creates turbulence. They all have a nifty flexible blade with bumpers on the leading edge. Unfortunately my three-year-old boy loves to stick his hands in the rotating blade. While this is fun I’m not sure it’s a good life-lesson.

  5. Thanks for the link, interesting. Using box fans right now so this is very handy.
